H EATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 229,193, dated June 22, 1880.

Application filed February 2,1880.

To all whom it may concern Be it known that I, JOHN HENERY SHIM- MONS, of Lawrence, Douglas county, Kansas, have invented a new and useful Heatin gStove and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a partof this specification, in which the figure is a vertical central section.

My invention is an improvement in heatingstoves of that class in which a set of pipes lead the air through the fire-chamber into an air-chamber above, from which airchamber pipes conduct the heated air through a drum placed above the air-chamber, which drum receives the'products of combustion, which further heat the air as it passes through the pipes.

My improvement consists in making the heating-drum above the air-chamber of greater capacity than the fire-pot below the air-chamber, and combining with the air-chamber external'air-supplying pipes, which re-eni'orce the volume of air passing through the drum, giving a larger volume of hot air than could be obtained from the limited number of pipes whichlead through the fire-pot simply, as hereinafter fully described.

In the drawing A represents the fire-pot of the stove, which is contracted at its lower portion into a grate, through which the ashes are discharged into the ash-pit B. On each side of the ash-pit, and in the back of the same, are formed chambers or compartments a a a, which open through the bottom of the stove into the room, and from which there rise a series of air-pipes, b b b, which pass through the tapering bottom portion of the fire-pot to the interior thereof, and finally open into an annular air-chamber above the fire-pot, the bottom of which air-chamber is formed by the annular partition 0, and the top of which is formed by the annular partition (I, which dips downwardly to the center, like a funnel, and is connected to the short central pipe, 6, which constitutes the discharge-flue from the fire-pot,

and opens thence into a drum, 0, placed above.

Extending downwardly from the air-chamber, between the partitions o and d, and outside of the fire-pot, are two fresh-air fiues,D D, which open through the bottom of the stove.

The air, as it rises through the air-pipes b, it will be seen, is heated by the directcontact of the fire, and, after passing through the airchamber, is again subjected in the pipes E of the drum to the direct heat of the hot gases which circulate in said drum about the pipes. After being thus thoroughly heated the air passes into the room from the tops of the pipes E, while the smoke and products of combustion pass through the pipe F.

The object of the flues D D is as follows: The heating-drum C, it will be seen, is very much larger than the fire-pot A, and hence is able to accommodate a greater number and size of ail-pipes than the limited size of the fire-pot will permit. To give a larger supply of air to the drum, therefore, I employ thin pipes D, the air from which is mingled with the partially-heated air in the air-chamber, which has already passed through the lire-pot lines, the combined currents then passing up through the pipes of the drum 0 to be reheated.

In constructing the funnel-shaped partition d, which forms the top of the air-chamber, the object in making the same funnel-shaped or sloping to the center is to give the soot and deposited particles an opportunity to slide down into the fire-pot and be consumed.

In modifying my invention 1 may separate the heating-drum G from the fire-pot a suffioient distance to allow the drum to be located on the story next above the stove,-in which case the air-chamber and the communicating central smoke-flue, e, are prolonged.

Another advantage of my, stove is, that it can be carried through as many stories as desired, either by one long central shaft or drum or by heating-drums in the different stor es. When several drums are thus used the air for one story may be taken through pipes b, D, and E, and for the next story it may be taken through the T-pipes P, which open sidewise into the same room where the stove is, and

lead through the lower drum to the drum in the story above.

Having thus fully described my invention, what 1 claim is- The combination of the fire-pot A and the drum (J, made larger than the fire-pot and having direct communication therewith, as described, the annular air chamber communi- 5 eating with the pipes 11 of the fire-pot and the pipes E of the drums, and the independent external pipes D, communicating with the upper annular air-chamber and supplying an additional quantity of air to the drum, as described.
